A problem that I've been running into wrt Java is the JVM hard memory limit.
Since users can (try to) load essentially arbitrary amounts of data into
my GUI app, we need to set the maximum heap size of Java at an absurd
place for *all* runs.

I don't have comparisons yet -- someone has been thinking about rewriting
various portions of my Jython app in wxPython -- but it seems to me like
Jython and Java together are using outlandish amounts of memory.  Something
to think about wrt Zope...
